Researchers from MPQ and LMU have experimentally demonstrated a strongly interacting quantum phase – known as the Mott-Meissner phase. This phase emerges under the combined influence of strong interactions and an artificial magnetic field. The results mark a major breakthrough: Previous experimental studies of interacting particles in artificial magnetic fields had been limited to system sizes involving only two particles. more

Researchers at MPQ, in collaboration with the chemicals company Covestro, have developed a method for simulating chemical models using fermionic quantum simulators. The key advantage: The energetic states produced in the lab intrinsically mirror molecular behaviour. Mapping chemistry algorithms onto their fermionic quantum simulator marks a major step toward harnessing quantum computing for fundamental chemistry. more

A research team at MPQ has confirmed surprising properties of thermalisation in two-dimensional quantum systems using a quantum simulator with neutral atoms. The study demonstrates how the initial state can significantly influence the thermodynamic behaviour of such systems—unlike in classical physics. The results were recently published in Nature and provide new insights into the behaviour of quantum systems out of equilibrium. more

For decades, quantum mechanics assumed all observable particles fall into two categories: fermions and bosons. Now, this dichotomous view of particles is being questioned. Researchers from MPQ and Rice University have investigated the intricacies of particle exchange statistics and shown that a third category, paraparticles, can exist under specific physical conditions. more

A team of researchers at MPQ has found first signs of stripe formation in a cold-atom Fermi Hubbard model. Using a quantum gas microscope and a special mixed-dimensional geometry, they were able to observe special properties associated with superconductivity - a huge advance in the fundamental understanding of this phase of matter and in the academic application of quantum simulators. more
